United Electric's One Series electronic switch platform for threshold detection and switching is the only field device of its kind that is able to diagnose and report its own health and status. One Series pressure, temperature, and differential pressure switches are designed for critical alarm and shutdown applications in harsh, hazardous environments.
Available in Type 4X enclosures for explosion-proof and non-incendive area classifications (shown here), these switches are designed to provide protection for plants, capital equipment, and people. With a digital process display and available 4-20 mA output, the One Series can provide the functions of a switch, a gauge, and a transmitter with only one connection to the process.
